whereby the studies receiving the most media attention are those reporting literally negative (ie, adverse) outcomes. In contrast, more rigorous studies that challenge these negative findings, even if publicized, rarely achieve comparable societal penetration or awareness /3

Since then have you heard that no, GLP1 meds almost certainly don't increase the risk of suicide and might in fact contribute to improved mood? I'm betting that's less likely and the reason why is negative publication bias - media edition /2

My latest in @medscape.com on GLP1 meds and suicide: Did you hear GLP1 meds might increase the risk of suicide? I'd bet you did. It was all over the news consequent to just 3 case reports submitted by Iceland to the European Medicine Association who announced an investigation /1

@yonifreedhoff.com Here are violin plots showing distribution of the ww signal in Ottawa by year and by VOC. "wwlast30d" represents signal sampled over past 30 days.

A 5-year, continuous public health dataset unaffected by policy changes--unlike clinical indicators--is a beautiful thing.

They were offering financial assistance only for those prescribed tirzepatide for diabetes

You might remember my blog on how Lilly effectively levied a fat tax on obesity whereby they were charging more for tirzepatide prescribed for obesity than for diabetes in 🇨🇦. Well they've cancelled that and launched a financial assistance program for Zepbound open.substack.com/pub/yonifree...

Are we at the lowest levels of the entire pandemic? Looks like maybe. Or at least very close. Pre-delta.

it would be valuable to compare the impact labels have on people with markedly decreased levels of hunger and cravings (GLP1 users) vs. those whose hunger and craving levels are not medically reduced. My bet of course is that the latter group will see a markedly diminished /3

nutrient only warnings were nearly as effective as those that tied warning to diseases like obesity - but only in an artificial study setting. In the real world, if the hope is that front of package warnings protect against weight gain/help with weight loss /2

Do front-of-package food warnings change behaviour? Do they increase stigma vs. obesity? How about if the warnings don't reference obesity at all but simply, as they should, reference nutrients? My latest for @medscape.com explores new research that found /1

Good news for Canadians looking to start Zepbound (tirzepatide) for obesity. Lilly will be introducing a program to help defray costs. Medication should be on shelves mid summer. I'll blog about this in more detail but wanted to briefly mention

And it certainly doesn't sound like any of the teens or their families received any real nutritional support or counselling that might have helped them maximize medication efficacy. Even sounded like one MD involved explicitly avoids providing same. /4

At least 2 of the teens had what sound like fairly severe side effects that they soldiered through - but with careful follow up I'd venture they could have been either avoided by slower dose titration, mitigated by way of dietary tweaking, or treated by way of concomitant Rx /3

Also striking though was that at least from the article, which of course may not have shared all of the details, the teens and their families received minimal or no ongoing support around the drug's prescription /2

Just read a rare piece that rather than demonize weight loss drugs, instead highlighted the use of Wegovy in teens by emphasizing the teens' joy for the benefits the drug provided them with /1

and not even one suggested a discussion with one's MD about weight loss medications or surgery. Difficult to reconcile that with the data except as an extension of the pervasive bias that obesity is a disease of willpower alone and as such, meds and surgery are somehow wrong /6

And there's no reason not to expect sustained pharmaceutically aided losses to confer similar results. Yet when I looked at some of the more publicized charities and organizations, though weight was listed as a risk factor, most provided zero guidance on how to manage it /5

There is benefit too to non-surgical weight loss where even modest and sustained weight loss is protective against breast cancer where sustaining a 2-4.5 kg loss was associated with an HR of 0.82; 4.5-9 kg of with an HR of 0.75; and > 9 kg an HR of 0.68. /4

Studies show hormone receptor +ve breast cancer risk increases 12% per 5-points of BMI in postmenopausal women, and he data on weight loss' prevention benefits is dramatic whereby bariatric surgical patients' hazard ratio for breast cancer's development was an astonishing 0.52 /3
